Application filed December 10, 1923. Serial No. 679,738.

To all whom it may concern:

Be it known that l, WILHELM B. BRONAN- one, a citizen of the UnitedStates, residing at Montclair, county of Essex, and State of New Jersey,have invented a new and useful Improvement in Cigar Bunch FormingLoopers, of which the following is a specification.

llhis invention relates to a cigar bunch forming looper for cigar makingmachines.

Certain cigar making machines heretofore known have what is known as aChianti belt,

the purpose of which is to roll a charge of filler into a binder toinitially form a bunch;

means for forming a loop therein to enclose the filler, this meansincluding one or two devices engaging the belt. The Chianti belt, withits loop forming device or devices, however, could form bunches: of onlyone shape. The trade demands cigar bunches of many different shapes, andheretofore it has been necessary tochange certain parts of the cigarmaking machines when it was desired to produce cigars of differentshapes. The necessity for such changes involved a decrease in quantityproduction while the change was being made, and consequently an increaseof cost.

It has. been discovered that these losses can be eliminated by using twolooping devices engaging a Chianti belt and relatively adjustable topermit changes in their spaced relation and angularity, so that themechanism can be adapted to make" bunches of many difi'erent shapeswithout machine change or appreciable loss of time. This is the mainobject of the present invention and with this and other objects notspecifically mentioned in view, the invention consists in certainconstructions and combinations which will be hereinafter fully describedand then specifically set forth in the claims hereunto appended.

In the accompanying drawings, which form apart of this specification andin which like characters of reference indicate the same or like parts,Fig. 1 is a side elevation, partly in section, of a bunch forminginvention; Fig. 2 is a plan view of a part of the structure shown inFig. 1, certain parts being broken away; Fig. 3 is a cross-sectionalView taken on the line 3'3 in'Fig. 2;

and-Figs. 4, 5, 6 and 7 are diagrammatic and coacting with said Chiantibelt islooper constructed. in accordance with theviews illustrating theoperation of the Chianti belt and loop forming mechanism.

In carrying the invention into effect, there to form a loop therein,said looping devices being relatively adjustable in said support topermit changes in their spaced relation and angularity in order to adaptthe device for the manufacture of bunches of man dilierent shapes. heparts above mentioned may be Widely varied in construction within thescope of the claims, for the particular device selected to illustratethe invention is but one of many possible concrete embodiments of thesame. The invention, therefore, is not to be restricted to the precisedetails of the structure shown and described.

Referring to the drawings, 8 indicates a Chianti belt of the usual type,one end of the belt being fast tit-9 to the edge of a rolling table 10;the other end of the belt is fast at 11 to a drum 12 which is rotatedfor belt tensioning purposes by means of a chain 13 operated by a camcontrolled weightl l, the control notbeing shown butwell known in theart. t

There is further provided a traveling support 15 which is'moved over theChianti belt 8 by means of a slide 16 mounted in a slideway formed bybars 17 located along one side of the table 10, and suitably supportedfrom the main frame of the cigar ina'chinerin connection with which thedevice is used. This slide is reciprocated by means of a link 18, oneend of which is pivoted thereto, the otherend of the link being pivotedto a cam actuated lever 19 deriving its motion from a cam'on one of thecam shafts of the machinein connection with which the plate 28, with itsgrooves 26 and 27, controls the path of thesupport as the latter movesover the table 10, and the path of the sup-' looping devices engagingthe belt 8 and relatively adjustable in said support to permit changesin their spaced relation and angularity to accommodate cigar bunches ofdifferent diameters and diflerent longitudinal contour. As shown, one ofthese devices'is mounted in fixed position relative tothe support andthe other is ad justably mounted relative thereto, andthe devicesunderlie the support. \Vith this end in view. the support is providedwith depending lugs 3132 in which are fixed rods 33, and on and betweenthe ends of these rods is mounted a roller 34. roller 34 is thereforemounted in fixed position relative to the support, butwill of coursefollow the tortuous path of the support as the latter moves over thetable 10.

v The support 15 is further provided with slots 35-35, and in each. ofthese slots is mounted a bolt 36 which serves to lock a rod 37 in ablock 38 depending from the support 15. Mounted upon adjacent ends andbetween the rods 37 is a roller 39.

The roller 39 may be quickly adjusted to vary its spaced relation andangularity with respect to' the relatively fixed roller 34 toaccommodate bunches of dificrent diameters and different degrees oftaper when they are in process of formation, asindicated in Fig. 6.

By means of the structure described, the device may be very quicklyadjusted to cause the, Chianti'belt to form bunches of differentdiameters and different longitudinal contours in order that manydiffer-' ently shaped bunches-may be made on the same machine by simplereadjustment of the looper and substitution of one stationary cam foranother, the latter being un necessary in many cases.

What is claimed is: 1. A bunch forming looper comprising The Abunchforming looper comprisinga Chianti belt. a traveling support, and twobelt looping devices engaging said belt and relatively adjustable insaid support to permit'changes intheir spaced relation and angularity,one of said devices being mounted in fixed position relative tosaidsupport and the other being adjustably mounted relative to saidsupport.

A buncht'orming looper comprising a Chianti belt, a traveling support,and two belt looping devices engaging said belt and relativelyadjustable in said support to permit changes-in their spaced relationand angularity, said devices being mounted to underlie said support. 1

- -1L. A bunch forming looper comprising Chianti belt, a travelingsupport, and two belt looping devices engaging said belt and relativelyadjustable in said support to per mit changes in their spaced relationand angularity, said devices including rods engaging said support, androllers rotatable on said rods.

Chianti belt, a traveling support, and two belt looping devices engagingsaid belt and relatively adjustable in said support to per mit changesin their spaced relation and angularity, said support being provided'with slots in which one of'said devices is adju'stably mounted.

6. A bunch forming looper comprising a Chianti belt, a travelingsupport, and two belt looping devices engaging said belt and relativelyadjustable in said support to permit changes intheir spaced relation andangularity, said support being provided with depending lugs in whichboth ends of .said devices are mounted.

7. A bunch forming looper comprising a Chianti belt, a travelingsupport, and two belt looping devices engaging said belt and relativelyadjustable in said-support to permit changes in their spaced relationand angularity, and stationary means for controlling the path of saidsupport.

In testimo-nywhereof, I have signed my name to this specification.
